The folks I support often do presentations in whatever venue they can book for cheap or free. Sometimes it’s just a large living room in a supporters house. So having the right gear is important.
For the projector, I highly recommend one with a “short throw”. That allows you to place the projector just 2 or 3 feet from the screen so it isn’t in the way of the audience or the presenter. I also recommend 1080p resolution, and a reasonably high brightness (at least 2000–3000 lumens) so the image will stand out even with ambient light in the room.
When I researched one for my org, I ended up with an Optoma. I don't remember the exact model, but this Optoma GT1080 looks very similar to it.
Finally, if you have the room to transport it, a roll-up screen like this is the best. But if you just need a cheap, portable surface to project onto, get this cloth and some cord and clamps to mount it.
Since this info isn’t readily available, here are all of the small-ish Pelican cases that most projectors will fit in, and their internal dimensions. I recommend at least 1" more that the dimension of the projector to leave enough room for padding.
